Experimental study of a combined heat-power-cool system

In this paper, a solar-powered cogeneration system is designed. This system can meet the needs of a small family for cooling, heating, power, and hot water, and according to the surrounding environmental conditions, the system can transform into different modes. Subsequently, the experimental platform was set up and the performance test of cooling and hot water mode function of the system was completed. With an experimental lasting time of 45 minutes and the compression frequency of 40Hz, pressure and temperature values needed at different ports were measured and collected. The result shows that, during the cooling process, the maximum power was 1292.29W, and the maximum cooling COP was 2.03. While heating water for the family, the maximum power was 1350W, and the corresponding COP was up to 2.12. The results provide a basis for the design and application of solar thermal power combined cooling system.
